Treasury Bills vs FGN Bonds in Nigeria: Which Is Better in 2026?

Estimated Reading Time: 12 minutes

Both are backed by the Federal Government. Both are among the safest places to put your money in Nigeria. But Treasury bills and FGN bonds are built for very different purposes — and picking the wrong one can mean leaving money on the table or locking cash away when you might need it.

I’ve invested in both over the years. I’ve used T-bills when I was saving for a specific goal 12 months away. I’ve turned to bonds when I wanted steady, tax-free income that would keep arriving twice a year without me doing anything. Neither is universally better. The right choice depends entirely on your timeline, how much you have, and whether you need regular income or a lump sum at the end.

One lesson I learned is that investors often focus only on yield. But after holding both Treasury bills and FGN bonds, I found that the investment horizon matters far more than a 1% or 2% difference in returns. Getting that wrong can cost you more than any interest rate spread ever could.

This guide compares Treasury bills vs FGN bonds in Nigeria side by side — returns, tax treatment, minimums, liquidity, and the real scenarios where one makes more sense than the other.

If you’re still learning the basics of either instrument, the guide to Treasury bills explained and the FGN bonds guide will give you the full background.

A Note on Other Types of FGN Bonds

When most investors compare Treasury bills and FGN bonds, they’re usually referring to Standard FGN Bonds — the long-term bonds issued by the DMO and traded on the FMDQ.

However, the government also issues:

• FGN Savings Bonds – Retail bonds with a ₦5,000 minimum and quarterly payments. Designed for smaller investors.
• FGN Sukuk Bonds – Asset-backed, Sharia-compliant bonds that pay rental income instead of interest. Proceeds fund infrastructure projects.

Both are tax-exempt and backed by the Federal Government, but they serve different investor needs. For detailed explanations, see the FGN Savings Bonds guide and the FGN Sukuk guide. This article focuses primarily on Standard FGN Bonds, which are the most common comparison point for Treasury bills.

Key Differences: Treasury Bills vs FGN Bonds

Returns and Payment Structure

Treasury bills pay everything at the end. You buy at a discount, wait for maturity, and collect your full face value. There’s no income along the way. Your true yield is higher than the quoted discount rate because you invested less upfront than what you’ll receive.

FGN bonds pay you every six months. If you hold a ₦10,000,000 bond with a 15% coupon, you get ₦750,000 twice a year — tax-free — for the life of the bond. When the bond matures, your principal comes back in full.

Which structure you prefer depends on whether you need cash flow now or a lump sum later. A retiree who wants to supplement their pension will likely prefer semi-annual bond payments. Someone saving for a house deposit in 18 months will prefer a T-bill that matures right when they need it.

Tax

This is where FGN bonds pull ahead decisively.

Treasury bill returns are subject to a 10% withholding tax. If your T-bill earns ₦100,000 in profit, you receive ₦90,000 after tax.

FGN bonds are fully tax-exempt under current Nigerian legislation. Every kobo of interest is yours. Over a decade or more, that difference compounds dramatically.

Minimum Investment

Treasury bills are far more accessible. You can buy through a bank with ₦100,000, or through an investment app with as little as ₦10,000. They’re genuinely open to almost anyone with a BVN and a smartphone.

FGN bonds at the primary auction require ₦50,001,000 — not a retail product. The secondary market opens the door for individual investors, but you’ll typically need at least ₦100,000 to get started, and you’re dependent on what brokers have available.

Liquidity

Both can be sold before maturity on the secondary market, but the experience differs.

Standard FGN bonds are highly liquid — they trade actively on the FMDQ, and you can usually find a buyer if you need to exit early. The price you get depends on current interest rates. If rates have risen since you bought, your bond will trade at a discount.

Treasury bills can also be sold before maturity, though the secondary market is generally less active for T-bills than for bonds. You may not always get the price you want, especially for smaller holdings.

Safety

Both are backed by the Federal Government and carry near-zero default risk. Nigeria has never failed to meet its naira-denominated debt obligations. From a credit risk perspective, T-bills and FGN bonds are equally safe. The difference is in market risk — long-term bonds are more sensitive to interest rate changes than short-term T-bills.

Example: ₦1,000,000 in Treasury Bills vs FGN Bonds

Let’s compare a ₦1,000,000 investment in both instruments.

Assumptions:

• Treasury Bill Yield = 20%
• FGN Bond Coupon = 16%

Treasury Bill:

• Gross Return: ₦200,000
• After 10% Tax: ₦180,000
• Timing: Received at maturity

FGN Bond:

• Annual Coupon: ₦160,000
• Tax: ₦0
• Net Return: ₦160,000
• Timing: ₦80,000 every six months

Although Treasury bills may sometimes offer higher short-term yields, FGN bonds become increasingly attractive for investors who value tax-free income and longer-term certainty.

When Treasury Bills Win

Treasury bills are the better choice when:

• You’ll need the money within 12 months. T-bills are built for short-term savings. Bonds lock your capital for years. If your goal is less than a year away, stick with T-bills.
• You’re starting with a smaller amount. With apps accepting as little as ₦10,000, T-bills are far more accessible than bonds.
• You want simplicity. A T-bill is a single transaction with a single payout. You buy it, you wait, and you collect. No coupon dates to track. No semi-annual payments to manage.

When FGN Bonds Win

FGN bonds are the better choice when:

• You want regular, tax-free income. FGN bonds are among the few government-backed investments that provide predictable, tax-free income every six months. For retirees, income-focused investors, or anyone building a long-term passive income stream, bonds are the superior instrument.
• You’re investing for 5 years or more. Bonds reward patience. The longer your horizon, the more you benefit from locking in a fixed coupon rate and letting the tax exemption work in your favour.
• You have significant capital and want tax efficiency. If you’re investing millions of naira, the 0% tax on bond coupons is a substantial advantage over T-bills, which lose 10% of every return to withholding tax.

Can You Own Both Treasury Bills and FGN Bonds?

Yes. Many experienced investors hold both.

Frequently Asked Questions

Which is better, Treasury bills or FGN bonds?

Are Treasury bills safer than FGN bonds?

Both are backed by the Federal Government and carry the same near-zero default risk. The main difference is that long-term bonds are more sensitive to interest rate changes if you sell before maturity.

Not if you hold until maturity — the government returns your full principal. If you sell before maturity and interest rates have risen, you could receive less than you paid.

What is the minimum amount for FGN bonds?

₦50,001,000 at the primary auction. On the secondary market, individual investors can access bonds through stockbrokers starting from around ₦100,000.

Do I pay tax on Treasury bills?

Yes, a 10% withholding tax applies to T-bill returns. FGN bonds are fully tax-exempt under current legislation.

How often do FGN bonds pay interest?

Every six months. If you hold a bond with a 15% coupon, you receive half of that annual amount twice a year.

Which gives higher returns: Treasury bills or FGN bonds?

Treasury bills may sometimes offer higher short-term yields depending on market conditions, while FGN bonds offer tax-free coupon income over longer periods. The better return depends on interest rates, taxes, and how long you plan to invest.

Which is better for retirees?

FGN bonds are generally better for retirees because they provide regular, predictable, tax-free income.

Which is better during high inflation?

Your Next Step

Ask yourself one question: When do I need this money back?

If the answer is less than one year, start with Treasury bills. Use our Treasury Bill Calculator to see what your money can earn, then buy through your bank or an investment app.

If the answer is five years or more — and especially if you want regular income — explore FGN bonds. Speak to a licensed stockbroker about what’s available on the secondary market, or visit your bank to enquire about the next DMO auction.

If you’re somewhere in between — say, 2-3 years — consider FGN Savings Bonds. They offer a middle ground with a ₦5,000 minimum and quarterly tax-free payments. See the FGN Savings Bonds guide for details.
